A bigger rise from colder incoming water leaves the heater with less flow.
- Cold water
- Cold water must be at least 10°F colder than the hot water setting.
- Flow estimate
- The estimate uses the lowest certified flow among the listed models. It is about 0.4 gal/min at a 70°F rise.
Flow limits
- The estimate excludes the flow needed to turn the heater on, heat lost in pipes, and installation.
- Cold water from a well or long pipe run can differ from the temperature you enter.
- Without a stated flow limit, estimates for warmer water may exceed the heater’s actual flow.

Certified figures by listed model
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|
| UPVS-35K 1** | 0.92 | 0.4 | 98% | Very small |
UEF is the uniform energy factor. A dash means the model has no such figure.
It heats 0.4 gallons per minute of water by 67°F in the test. The electric tankless type has a median flow of 0.7 gallons per minute. Among 337 electric tankless models, 233 give more flow at a 67°F rise.
In tests, 92% of the energy it uses ends up as hot water (UEF 0.92). Its test ran at the very small level of daily hot water use. Of 272 electric tankless models with the same draw pattern, 249 have a higher UEF and 7 a lower one. On its draw pattern, the median electric tankless UEF is 0.96. When it runs, 98% of the energy it uses reaches the water (its recovery efficiency).
All of its test figures are shared by 4 other basic models. Of those, one or more are under the A. O. Smith and American brands. You can find the whole group on the page for the A. O. Smith UPVA-35E 1**.
